AI overview

A virtual private network (VPN) is a service that extends a private network across the public Internet, making it appear to users as if they're connected to a private network even when they're not. This matters because it allows people to access private network resources and communicate securely over public networks.

VPN connectivity overview, showing intranet site-to-site and remote-work configurations used together

A virtual private network (VPN) is an overlay network that uses network virtualization to extend a private network across a public network, such as the Internet, via the use of encryption and tunneling protocols. In a VPN, a tunneling protocol is used to transfer network messages from one network host to another.
